Abstract

This study was conducted to investigate the growth characteristics of strawberries and N2O emission by treating the compost for each type of livestock manure, which was an organic farming material, as a basal fertilization in plastic film house. Livestock manure compost, which made from cattle manure, swine manure, and poultry manure as raw materials, were applied to this experiment, treated by mixing or single on the basis of nitrogen content with the standard amount of fertilizer for strawberries. Total emission of N2O were 10.7% higher than those in poultry manure compost treatment compared to the inorganic fertilizer treatment, but 16.5~41.9% lower than those in other livestock manure compost treatment. The period of N2O emission mainly was up to the 17th day after fertilizer application, accounting for 70~87% of the total amount of discharge, and 13~30% of the total amount was emitted for 158 days later. N2O emission was decreased significantly NH4+-N content in the soil, and increased NO3--N. As compared with control, the number of leaves, leaf width and crown diameter of livestock manure compost treatments were not significantly different, leaf length of cattle+poultry, cattle+ swine, swine+poultry treatment higher, and SPAD (soil plant analysis development) values of cattle+poultry treatment highest. There was no significant difference in weight and sugar content of strawberry fruits among treatments.

시설재배지에서 토양 양분으로 유기농업자재인 가축분 종류별 퇴비를 밑거름으로 처리한 후 발생하는 N2O와 딸기의 생육 특성을 조사하기 위해 본 연구를 수행하였다. 가축분퇴비는 돈분과 우분, 계분을 원료로 하여 각각 만들어진 제품을 사용하였고, 딸기 표준시비량의 질소를 기준으로 단독 그리고 혼합 처리하였다. N2O의 총배출량은 무기질비료 처리구와 비교하여 계분퇴비 처리구에서 10.7% 많았으나 다른 가축분퇴비 처리구에서는 16.5~41.9% 적게 배출되었다. N2O가 주로 배출되는 기간은 비료살포 후 17일차까지로 전체 배출량의 70~87%를 차지하였고, 이후 158일간 13~30%가 발생하였다. N2O 배출량은 토양의 NH4+-N 함량과 부의 상관성을 나타내었다. 딸기의 생육 중 엽수, 엽폭, 관부직경은 처리구간 유의한 차이를 보이지 않았고, 엽장은 무기질비료 처리구보다 가축분퇴비 처리구에서 컸으며, SPAD 값은 우분퇴비와 계분퇴비를 혼합하여 시용한 처리구에서 가장 높았다. 딸기 과실의 무게와 당도는 처리구간 유의한 차이를 보이지 않았다.
